Sydney Wells (Jessica Alba) is a successful classical violinist who has been blind since the age of five. Fifteen years later, Sydney undergoes a cornea transplant, which causes her eyesight to return, a bit blurry at first. As time goes on, Sydney's vision begins to clear; however, she also begins experiencing terrifying visions, mostly of fire and of people dying. The bulk of the rest of the film concerns Sydney unravelling the mystery of the visions, and trying to convince others, primarily her visual therapist, Paul Faulkner (Alessandro Nivola), who becomes a helpmate in her quest. She knows that she is not going insane. She finds herself in Mexico, where the donated corneas were originally from. The fire and people dying are the result of an industrial accident that the former donor foretold and shortly after that hanged herself because she could not stop the accident from occurring. Sydney puts the spirit to rest, and began her trek home. As Sydney and Paul wait in a queue of vehicles to cross the border, a high speed police chase ends with the fugitive crashing through the border barriers and into a tanker full of gasoline. Sydney, able to still see the death silhouettes, begins to try to get everyone she can off the highway. The tanker explodes from a spark in the getaway car's engine, and Sydney is blinded by flying glass. After recovering at a hospital, she returns to her life as a blind violinist, though with a more optimistic "view" of her condition.
